George W. Bush defeated Al Gore in a close 2000 election that was ultimately decided by the Supreme Court after recounts in Florida. Bush pursued tax cuts and education reform but his presidency was defined by the 9/11 terrorist attacks. This led to wars in Afghanistan and Iraq, as well as increased security and surveillance policies domestically. Bush was reelected in 2004 but saw his approval ratings drop due to the economic crisis and handling of Hurricane Katrina. By 2008, Barack Obama was elected on a message of change, defeating John McCain amidst growing unpopularity of the Iraq War and economic challenges.
